TANK-HEATER.

Specification of Letters Patent.

Patented June 12, 1906.

Application filed July 31,1905. Serial No. 272,095.

v To all whom it may concern:

tion.

Our object is to provide a device of this class of simple, durable, and inexpensive construction in which the ashes may be readily and quickly removed from beneath the grates and carried away without danger of contaminating the water in the tank.

Our invention consists in the construction of the tank-heater and in the arrangement and combination therewith of the ash-tray whereby the objects contemplated are attained, as hereinafter more fully set forth, pointed out, in our claims, and illustrated in the accompanying drawings, in which.

Figure 1 shows a side elevation of the complete tank-heater and ash-tray with a portion of the tank in position supporting the tankheater. Fig. 2 shows a top view of same without the tank. Fig. 3 shows an enlarged sectionai view of same on the line 3 3 of Fig. 2 and also showing a tank in position supporting the tank-heater. Fig. 4 shows a plan view of the grates. Fig. 5 shows an end elevation of the means for rocking the grates, and Fig. 6 shows a detail perspective view of the ash-tray.

Referring to the accompanying drawings, we have used the reference-numeral 10 to indicate the tank. The heater proper comprises sides 11, one upright end 12, and one end 13, inclined upwardly and outwardly, and a bottom 14. The frame thus formed is made water-tight and is designed to rest within a water-tank. It is secured in position by a rod on each side, engaging a lug 16 on the side 11 and secured to the bottom of the tank 10. The cover for the tank-heater is indicated by the numeral 17, and communicating with the cover at the end adjacent to the upright portion 12 is the flue 18. Near the center of the cover is the fuel-opening 19, normally covered by the hinged lid 20 within the tank-heater.

The reference-numeral 21 is used to indicate the grate, which is of the rocking type and comprises two sections. Each section is pivotally supported at its ends, as will hereinafter appear, and each is provided with a cogtoothed segment 22, which segments are in mesh with each other, and one of them has the rod 23 pivoted to it, extended upwardly through the cover 17 and provided with the handle 24, by which the grates may be rocked. One end of the grate-sections is pivotally supported in a sheet-metal hanger 25 secured to the upright end 12 and inclined inwardly and downwardly therefrom, protecting the segments 22 from the fire on the grates. The other end of the grates is pivotally supported in the lower end of a partition 25, secured to the side walls 11 and ex-' tended parallel with the end 13 from the top 17 to a point spaced apart from the bottom 14, thus forming a passageway 26 from the top of the tank-heater to a point communicating with the ash-pit below the grate. The top of the passage-way 26 is normally closed by a detachable plate 27, having a handle 28. This plate may, if desired, be shifted longitudinally of the top of the tank-heater, and it also forms a damper for controlling the admission of air to the ash-pit. We have provided for removing ashes from the ash-pit as follows: On the sides 1 1, near the upper portion of the inclined end 13, are the lugs 29, and adjacent thereto on the inclined end 13 is the lug 30. These lugs are for the purpose of supporting the ash-tray, as will hereinafter appear.

The ash-tray is preferably made of sheet I metal and comprises a bottom 31, upright sides 32, an outer end piece 33, inclined substantially parallel with the end 13, an inner end piece 34, also inclined in the same way, and extension inner end pieces 35, on which are formed the lugs 36. In use the ash-tray is placed in position against the top of the end 13, with the extension ends projecting over the sides of the tank-heater. The bottom of the trayrests upon the lug 30, and the lugs 36 of the tray project under the lugs 29 on the tank-heater, thus supporting the ash tray in position with its open top surrounding the upper end of the passage-way 26. If it is desired to remove ashes from the tankheater, the operator inserts a scraper of suitable size through the passage-way 26 and into the ash-pit and with this scraper draws ashes upwardly over the inclined end 13 to the top of the passage-way 26 and permits the ashes to drop into the ash-tray. The extensions at the sides of the ash-tray proj ect beyond the sides of the tank-heater, so that any ashes that maybe spilled over the sides of the passage-way 26 will be caught in the ash- ITO tray. Then when the ashes have been removed from the ash-pit the operator detaches the ash-tray from the tank-heater by simply elevating its outer end far enough to withdraw the lugs 36 from contact with the lugs 29, whereupon the ashes may be removed and discharged from the ash-tray without danger of having them spilled into the water in the tank.

Having thus described our invention, what we claim, and desire to secure by Letters Patent of the United States therefor, is-

1. The combination with a tank-heater having an inclined passage-Way extending from its top downwardly and toward the center of the tank-heater and communicating with the ash-pit thereof, lugs on the sides of the tank-heater, a lug at the end of the tank-heater and an ash-tray formed with an open top shaped to fit the end of the tank-heater surrounding the end of the tankheater adjacent to the top of said passageway. and also shaped to overlap the sides of the tank-heater surrounding the said passage-way and lugs on the tray to pass under the lugs at the sides of the tank-heater.

2. The combination of a tank-heater provided with a passage-way extending from the top to the ash-pit of the heater, lugs on the sides of the tank-heater near the top of the passage-way, a lug at the end of the tankheater near the top of the passage-way and an ash-tray open at its top and shaped to fit the end of the tank-heater adjacent to the passage-way and to extend around the sides thereof, its central portion designed to rest upon the lug at the end of the tank-heater and extensions on the ash-tray designed to pass under and engage the lugs at the sides of the tank-heater to thereby detachably support the ash-tray on the tank-heater.
